这是我现在的最终解决方案，没有多余的隐藏单选按钮:

This was my final solution now, no extra hidden radio buttons:

<tr data-bind="click: $root.selectProduct, css: { 'active-row': $root.selectedProduct() === $data }">

以及ViewModel中的selectedProduct实现:

And the selectedProduct implementation within the ViewModel:

function AppViewModel() {
    // Private
    var self = this;

    // Public Properties
    self.selectedProduct = ko.observable();
